Apache 不会强制 https://domain 到 https://www.domain（重写不起作用）

设置 Apache 2.4 和 Wordpress 后，我收到以下 SSL 错误消息：

$ wget "https://example.com"
Resolving example.com (example.com)... 192.168.15.5
Connecting to example.com (example.com)|192.168.15.5|:443... connected.
ERROR: no certificate subject alternative name matches
requested host name ‘ example.com’.
To connect to example.com insecurely, use `--no-check-certificate'.

为了使域名与我的 SSL 证书 ( www.example.com) 匹配，我尝试调整站点配置以将https://example.com重定向到https://www.example.com。但它不起作用：http-to-https 重定向功能如预期，但裸域到 www-domain 没有。

这是我的站点配置：

<VirtualHost *:80>
        ServerName example.com
        ServerAlias www.example.com
        Redirect permanent / https://www.example.com/
</VirtualHost>
                                                                                                  
<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
            ServerName www.example.com

            Protocols h2 http/1.1

            ServerAdmin webmaster@localhost
            DocumentRoot /var/www/html
            DirectoryIndex index.php

            RewriteEngine on            #### Doesn’t work at all ####
            RewriteCond %{HTTP_HOST} ^example\.com [NC]
            RewriteRule ^/(.*) https://www.example.com/$1 [L,R=301]

            SSLEngine on
            SSLCertificateFile      /etc/letsencrypt/live/www.example.com/fullchain.pem

    </VirtualHost>
</IfModule>

该站点本身运行良好，并且.htaccess仅包含由 Wordpress 创建的行。

任何输入表示赞赏。
